Desgining and implementing computer networks

I have developed network architectures for organizations of varying scales, focusing on ensuring efficient data transmission, scalability, resilience, monitoring and managemet. This includes the deployment of multiple network devices sourced from a diverse array of vendors, such as:

• Routers

• Switches

• Wireless Access Points

• Wireless Controllers

• Load Balancers

Each component has been carefully selected and integrated to optimize network performance and reliability, catering to both immediate operational requirements and long-term growth objectives.

Securing systems and computer networks

I have successfully implemented and developed a comprehensive range of security measures to bolster the cybersecurity posture of various organizations. My expertise encompasses the strategic deployment and management of:

• Firewalls: Establishing robust barriers to protect networks from unauthorized access and threats, while facilitating secure communication channels.

• Intrusion Detection/Prevention Systems (IDS/IPS): Implementing advanced systems designed to detect and prevent potential threats in real time, ensuring continuous network security monitoring.

• VPN Technologies: Deploying Virtual Private Network solutions to secure remote access and data communication, enhancing privacy and data integrity across public networks.

• Endpoint Security Solutions: Strengthening the security of individual devices within the network (endpoints), to prevent them from becoming entry points for security threats.

Designing, leading, and teaching academic courses

As the Course Leader, I have involved in the development and instruction of a comprehensive Bachelor's degree course in Computer Networks, drawing upon my expertise in the field. Additionally, in my capacity as a Senior Lecturer, I have been involved in delivering high-quality education across a range of modules, including:

• Networking Fundamentals: Providing a solid foundation in the principles and practices of networking, equipping students with the essential knowledge required to understand complex network systems.

• Network Design and Management: Teaching students the critical skills needed for designing, implementing, and managing effective and efficient network infrastructures.

• Network Security: Educate students on the various threats to network security and the strategies and technologies employed to safeguard against these threats.

• Secure Systems Administration: Offering in-depth insights into the administration of computer systems with a focus on maintaining security and operational integrity.

• Ethical Hacking and Network Intrusion Detection: Instruct students on the methodologies used by ethical hackers to assess network vulnerabilities and the techniques for detecting and responding to unauthorized intrusions.

• Digital Forensics and Incident Response: Training students in the investigation of cybercrimes and the execution of comprehensive incident response strategies.

My contributions in these areas underscore my commitment to fostering academic excellence and preparing students for successful careers in the rapidly evolving field of computer networks and cybersecurity.

Implementing and managing systems and services

I have successfully implemented and managed a comprehensive suite of systems and services across various platforms, demonstrating a broad technical expertise and commitment to maintaining robust, efficient network environments. My areas of responsibility have included:

• Active Directory on Windows: Setting up and managing user identities, groups, and policies to ensure secure and organized access across network resources.

• DNS on both Windows and Linux: Configuring and maintaining domain name system services.

• DHCP on Windows and Linux: Implementing dynamic host configuration protocol services to efficiently assign IP addresses to devices on the network.

• Radius Servers: to provide centralized Authentication, Authorization, and Accounting management for users who connect and use a network service.

• Monitoring Services including SNMP (Simple Network Management Protocol), Syslog, and NetFlow.
